l hisinvention relates to certain. new anduseful improvements ingang-plows, whereby the difficulties attending theoperation-of thosehitherto constructed .arc surmounted and a", thoroughly practicalimplement obtained.

a .The invention consists in the peculiar constructio'n'of the frame ofthe machine, and the manner in 'whichthe several shares are at-J,jtachedthereto, soth'at said' shares, may with the greatest facility beadjusted both verti-- cally and vlaterally, and the furrows plowedtheid'esired depth. and width, and-the shares also allowed to be movedin a vertical direc tion independently 'of the frame, so that th ey' maypass over obstructions.

The invention also consistsn a peculiarly constructed mold-board,'ashereinafter described, whereby the sward is raisedfand turned'withgre'atcrfacility than usual.

' Tothe lever 9 the upper end of a rod, q, is attached. The lower partof this rod is bent or curved at an, inclination corresponding to that'of the axis d, and a wheel, P, is placed on the lower-part of the rodq.' The rod q is al. lowed to turn freely, and an arm, r, is attachedo'r bolt, 0, which passes vertically through the the end of the'bar Fopposite to the end'which is attached to the axisd has nn'arm,G;-piv-.-To"the lever D, at about its center, a segor bars, g h, are placed.These rods or bars are curved downward, and are so bent and;

To the, upper end of eachfbentbar I a hori rods 9', the lower en'dsof'which are attached to I of two of .the horizontal bars K are'connectedfitted and allowedto turn on a rod, M, which holes, a, in a curved' orsegment bar, lit; the

catch retaining therod or axis q; i

To the upper ends of the two uprights 0 .0 a horizontal bar, S, isattached. The outer end of this bar S is supported by a'swivel-wheel, T,as shown in Figs. 1 and 4,01 the swivelwheels T may be employed, asshown in Fi 3, thewheels T being screwed to the ends of a bar, U, whichis connected to the bar S by a joint, 2;, at itseenter.. Theapplicationof. the two wheels would be preferable in undulating or'uneven ground,as the shares would not be affected thereby. I Through thebarS thcuppcrend of a verti 'al rod, V, passes. The upper end of this rod hasascrew-thread cut on it, and a nut, 00', is titted thereon, a lever orhandle, 1 being attached to thenut. The lower end of the rod V isattached to the bar 13. (SeeFigs. 2 and 4.'

The inner end of 'the lever Dis connected by a link, 2, with alever, \V,and the bar K of the outermost Share J is fitted in a loop or hook,a,,on said lever, as shown clearly in Figs. 1 and 2; i

To thefront end of the bar K of 'the'innermost share J a clevis, X, isattachedby a screw-rod, I), the upperend'of which has a nut, 0, upon it.

Y is a rod, the uppereud of which passes vertically through the clevisand has a nut, (1, upon it. The lower end of the rodYis forked, and acircular colter, Z, is fitted in 'said fork.

We would remark that instead of the usual mold-board two spii'als,w.r,may be employed, which will rotate as the implement is drawn along-andthe sward is pressing against them.

These spirals, acting on the screw principle, serveto assist the raisingand turning'of the sward.

The-spirals a" a" are of taper or conical form, add are fitted betweenbars a a adjoining the share, the upper and lower ends of the spiralsbeing provided with proper journals, so as .to allow of their easyrotation. The spirals may be formed by bending metal rods of t-herequisitc size in spiral form. By this improved feature of the machineits draft is very much decreased, especially in clayey land andlaudcoutaining moisten), and consequently heavy.

By turning the nut a: it will be seen that the bar .13 and shares J willbe raised and lowered, and theidcpth of the furrows may be regulated asdesired, and by; moving the lever W tious.

I) and bar IF will bc'actuated and the shares J will be moved laterally,so that the width of the furrows maybe regulated as desired.

The driver, by depressing the end of the lever 0, may temporarily raisethe frame and shares J to allow The machine is readily guided and turned.by merely moving the lever Q, the movement ot the lever causing theswivel-wheel to be tu'rnedin any desiredposition to guide theimplement.

By having the coltcr fitted in the forked rod Y, and having said rodfitted in the adjustable clevis X,-as shown, the coltcr may be adjustedlaterally, as circumstances may require.

By having the wheels 1 E inclined the lateralpressnrebf the wheelsagainst the earth is avoided. If the wheels were vertical, this sidepressure, caused by the resistance made by the sward in being turnedover by the several shares, would'create great friction. f The wheel Eespecially would create great friction,

as thatwheel adjofin's or runs in contact with thelaudside, and would,ifvertical, bear against it from top to bottom.- The obviating of thefriction consequent upon theside pressure is w an important feature ofthe invention.

- \Ve are aware that series of shares have been arranged in gang-plowsso that they could be adjusted vertically and laterally, an t wetherefore donot claim a series ofshares thus arranged, irrespective ofthe means employed foroperating them; neither do we claim a swivelwheelfor guiding and turning the machine, irrespective of the manner in whichit is arranged and applied to the machine; nor

.-do we claim a rotary colter simply but,

Having thus described our invention, what. we claim as new, and desireto secure by Letters Patent, is-

1. Attaching the bar F to the bars A by uneans of the lever D and arm G,and having the ends of the bars K connected by chains in to arms n,connected to a bar, L, to which a lcver,L, is attached, the lever 0being attached to one end of the bar A and to the rod q, as shown, andthe screw-rod V, attached to the bar B and passing through the bar g,whereby the shares may be adjusted vertically and laterally, and alsoraised temporarilywhen necessar as herein shown and described.

2. 'A'mold-board constructed of conical wire rollers a" mflarranged asshown or in an equivalent way,for the purpose of raising and-turning thesward, as set forth.
